not hesitate to give it with confidence as a distinct species. Its 

 short upright shoots ; its inflected leaves, and emarginate petals ; 

 its stems never bearing above two or three flowers ; and lastly, 

 its being nearly smooth, will always prevent its being confounded 

 with the three preceding species. In some respects, but espe- 

 cially in habit, it approaches near to S. ccespitosa, Linn. It dif- 

 fers however from it by its emarginate petals ; by the longer and 

 inflected segments of its leaves ; and likewise by the whole plant 

 being almost smooth, and nearly double the size.

The late Mr. G. Don discovered this species many years ago on 

 rocks on the summits of the mountains of Angus, near the con- 

 fines of Aberdeenshire, where it grows in little dense tufts, flower-
